Definitions

  • the present invention relates to a discharge unit for use in a steaming device, comprising:
  • the present invention relates to a soleplate for use in a steam iron, which is provided with at least one steam discharge unit.
  • a steaming device comprising a unit for receiving so-called wet steam, i.e. a water-steam mixture, from a steam generator, and letting out dry steam.
  • HU 193751 discloses a steaming device having a steam discharge unit which is denoted as a condenser vessel, and which has a cylindrical inner cavity and an inlet for letting wet steam into the cavity.
  • rotating motion is imparted to wet steam that is supplied to the cavity of the condenser vessel, so that water droplets are separated from the steam by centrifugal force.
  • the water is discharged from the vessel or evaporated by heating, and the steam is discharged in line with the axis of the rotating motion, i.e.
  • the condenser vessel is in the form of a housing with a cylindrical cavity, a tangential steam inlet pipe and a concentric dry steam discharge pipe.
  • HU 193751 furthermore discloses a manual steam iron which is provided with disc-shaped evaporator cavities in its base, wherein each of the cavities acts as the above-described condenser vessel.
  • a disadvantage of the condenser vessel known from HU 193751 is that spitting may occur.
  • Spitting is a well-known problem in the field of steam irons, and involves an undesirable situation in which water droplets are carried along by the steam that is released from a soleplate, as a result of which items to be ironed may get wet, and may even get stained.
  • the condenser vessel is designed to only let out dry steam, but in practice it occurs that water droplets escape from the vessel along with the flow of steam. There are various factors contributing to the problem. Among other things, as the condenser vessel is made to fit inside the soleplate of an iron, the condenser vessel has a shallow and compact design. As a consequence, the distance between the inlet and the outlet is relatively short, and the water-steam mixture does not remain in the vessel long enough for the water to evaporate and/or flow towards the discharge of the vessel.
  • a discharge unit which may be a soleplate of a steam iron, or a steamer head
  • condensation may occur along a steam flow path, resulting in water entering the discharge unit along with the steam at relatively high velocities.
  • foaming can occur in the steam generator due to concentration of scale and impurities, resulting in water being carried over along with steam to the discharge unit.
  • a low energy content is obtained, resulting in a situation in which it is difficult/impossible to realize sufficiently fast evaporation of water entering the chamber of the discharge unit. Due to any of the above-mentioned factors, water leakage from the discharge unit can occur while steaming is activated.
  • a solution is needed to ensure that water is retained effectively in the chamber of the discharge unit.
  • a steam discharge unit comprising a chamber, an inlet and an outlet associated with the chamber, a barrier which is arranged inside the chamber, in a flow path of a water-steam mixture from the inlet to the outlet, and a hydrophobic surface which is located inside the chamber as well.
  • the barrier is adapted to be in the way and block a direct route towards the outlet.
  • the barrier is arranged around the outlet.
  • the barrier may be shaped like a tube, and may extend inwardly from a wall of the chamber in which the outlet is located.
  • the barrier constitutes an obstacle in the flow path of a water-steam mixture from the inlet of the chamber to the outlet, i.e.
  • a combination of a barrier and a hydrophobic surface is applied, as a result of which spitting is completely avoided.
  • the hydrophobic surface can be realized by having a hydrophobic coating such as polytetrafluorethylene (PTFE) applied to a wall portion of the chamber, or by having a part made of high temperature resistant and hydrophobic material such as PTFE.
  • PTFE polytetrafluorethylene
  • the hydrophobic surface for example other hydrophobic polymers, and finishes, for example finishes adapted to create a lotus leaf effect, can be used as well.
  • the hydrophobic surface may be arranged such as to surround the barrier.
  • the chamber of the discharge unit according to the present invention is a so-called cyclonic steam chamber which comprises a curved wall.
  • the wall is heated, and due to the curved shape, heat transfer to the water is enhanced as the water is spread against the wall and pushed against the wall by the principle of centrifugal force.
  • the curved wall serves as the heated surface of the chamber, which can extract directly the energy from a heating element. In this way, energy availability for steaming against the curved wall is guaranteed.
  • a cyclonic steam chamber may be provided with an inlet having a tangential orientation with respect to the curved wall, in order to allow smooth entry of a flow of a water-steam mixture into the chamber.
  • a tangentially oriented inlet maintains the high velocity of the flow, and maximizes the centrifugal effect as mentioned in the foregoing.
  • the outlet is located at another wall of the chamber than the curved wall.
  • This feature combined with the tangentially oriented inlet, allows the water to make repeated loops inside the chamber, along the curved wall.
  • the length available for steaming is enormous, in a compact design of the chamber, which is very advantageous in view of heat transfer.
  • the outlet has a central position with respect to the curved wall of the chamber.
  • the water enters the chamber at the curved wall and is confined to the curved wall due to centrifugal force.
  • the outlet At a central position, the outlet is located as far as possible from the curved wall, so that the possibility of water reaching the outlet is minimized.
  • the curved wall of the cyclonic steam chamber may be provided with a taper in order to force the water to flow to another wall which is connected to the curved wall.
  • the taper can be used to guide the water further away from the outlet.
  • the discharge unit may comprise a hydrophilic surface for enhancing steam formation. It will be understood that such a hydrophilic surface is preferably positioned at a distance from the outlet.
  • the chamber is shaped like a cylinder having two end walls and a curved side wall extending between the end walls, wherein the barrier is shaped like a tube extending inwardly from one of the end walls of the cylinder.
  • the hydrophobic surface may be located at the tube-shaped barrier, and the tube-shaped barrier may be arranged such as to surround the outlet.
  • the discharge unit may further comprise an additional barrier which is located inside the chamber for directing the flow of the water-steam mixture.
  • an additional barrier which is located inside the chamber for directing the flow of the water-steam mixture.
